The Japan edition of Milk and Kisses contains two bonus tracks ("Flock Of Soul" and "Primitive Heart").[10] The Hong Kong edition contains a version of "Serpentskirt" sung by Elizabeth Fraser with C-pop artist Faye Wong as a duet. Wong later recorded an acoustic version of "Rilkean Heart" in her 1997 album Faye Wong, in which Guthrie and Raymonde also wrote a new song "Yu Le Chang" ("Amusement Park") for her. In 2013, Sarah Brightman covered their song "Eperdu" on her album Dreamchaser.
